Because the left- and right-handed molecules are still very similar, scientists have had trouble separating them from each other. But a team of researchers in Japan might have found a solution. In their new study, published in Science Advances, the team successfully separated an equal mixture of mirror-image molecules created by replacing hydrogen with deuterium in one form.","pubDate":"Wed, 21 Oct 2026 11:50:01 EDT","url":"https://phys.org/news/2026-10-mirror-image-molecules-difficult-counterparts.html"},"indexado":"2026-10-21T15:51:52.633Z"}}
